The correct answer is C) A good society is able to face schemes of world domination and foreign revolutions alike without fear.
The line from Roosevelt’s speech that is an example of pathos is "A good society is able to face schemes of world domination and foreign revolutions alike without fear."
The Pathos approach is used when we want to appeal to the emotion of the audience in order to convince it of our argument. That is what President Franklin D. Roosevelt did in his State of the Union Adress of 1941.
The other two approaches are Lohgos y Ethos. We use Logos when we appeal to logic, the reason, to convince the audience. Finally, Ethos is an appeal to the reputation of the speaker.
